1.采条部位这很重要,它关系到扦插能否成活。一般情况下,木本花卉宜采主干上、树冠下萌发的新生枝条,最好为2年生半木质化的。如月季采条时应取花谢后的枝条,这样的枝条营养丰富,易于发根。草本类花卉取带有顶芽的侧枝或主枝,如菊花应取自盆土中生长出的脚芽(见图1)。2.采条方法也会影响到扦插后成活的问题,如橡皮树、夹竹桃等植物采条时,应取主干上萌发的小侧枝,用手握住侧枝基部,用力向下撕(或用刀切割),使采下的枝条下端带有一些来自主干的树皮,即韧皮部、形成层和木质部,扦插后易成活(图2)。3.采条后切割应用利刀在枝条节下部位0.2～0.5毫米处切割,刀要快,草本类离节近些,0.2毫米左右,木本类可稍远些,在0.2～0.5毫米之间。由于节部营养充足,并且其他活性因子为促进细胞分裂提供了充足的营养和激素,便于生根(图3)。
1 mining section This is very important, it relates to whether the cuttings survive. Under normal circumstances, woody flowers should be picked on the trunk, the new branches under the crown of germination, preferably 2 years of semi-lignified. Such as rose picking should take after Xie Xie branches, such branches nutrient-rich, easy to root. Herbaceous flowers take the lateral branch or main branch with a terminal bud, such as chrysanthemum should be taken from the growth of peat buds (see Figure 1). 2 mining method will also affect the surviving cuttings, such as rubber trees, oleanders and other plant mining, should take the stem on the germination of the small side branches, hand holding the base of the lateral branches, forced tear down (or With a knife cut), so that the lower branches taken with some stems from the bark, phloem, the formation of layers and xylem, easy to survive after cutting (Figure 2). 3. After cutting the application of cutting knife in the branches of the next section of 0.2 to 0.5 mm at the cutting, the knife should be faster, near the section from the herbaceous species, about 0.2 mm, woody class may be slightly further, at 0.2 to 0.5 mm between. Roots are easily rooted because nutrients are abundant in nodes and other nutrients provide sufficient nutrients and hormones to promote cell division (Figure 3).
